On 24 September, 2013, a magnitude 7.7 earthquake occurred in Balochistan, Pakistan. The quake caused intense ground motions and had dramatic consequences – hundreds of people died, and more than 100,000 lost their homes. A secondary effect which caught much attention in the international media was the birth of an island off the Pakistani coast – Zalzala Jazeera or Earthquake Island. Another effect which went almost completely unnoticed was a small tsunami in the Arabian Sea. The tsunami reached wave heights of around 1 m at the Omani coast. In a paper which was recently published in Geology, my colleagues and me document the tsunami effects in Oman. We conclude on a submarine slide off Pakistan as the likely trigger mechanism.

New book: Intraplate Earthquakes
2014-07-28 | in Earthquake, PaperIntraplate earthquakes are those that occur far away from plate boundaries in what is often also referred to as slowly deforming regions or stable continental regions (SCR). Seismicity there is comparably low and earthquake recurrence intervals can easily exceed thousands of years for individual faults. However, intraplate quakes do account for a significant number of earthquake fatalities and killed more people than those that happened at plate boundaries during the last 100 years (England & Jackson , 2011). A new book has been published a few days ago, dedicated to summarizing our knowledge of these seismic events. more

5th PATA Days in Busan – registration deadline extended to 20 June
2014-06-08 | in Busan 2014, MeetingDear friends and colleagues,
The deadline for registration of the 5th PATA-days meeting is extended to June 20, and for abstract submission to the end of June.
The 5th International INQUA Meeting on Paleoseismology, Active Tectonics and Archeoseismology (PATA Days) will take place in Busan, Korea from 21-27 September 2014. Already some 75 scientists from all around the world have registered for this meeting – be the next one and don’t miss the latest news on old earthquakes.See details on the official website: www.pata-days.org.
Please don’t miss the last chance to visit dynamic Korea!

First paper on the earthquake environmental effects of the 2014 Cephalonia (Greece) M6.0 quakes
2014-06-04 | in Earthquake, PaperOn 26 January and 3 February, 2014, two strong and shallow strike-slip earthquakes of magnitude 6+ occured beneath the island of Cephalonia in Western Greece. Both events caused intense damage to buildings and infrastructure. A team of Greek geologists mapped earthquake environmental effects (EEE) such as liquefaction, road failures, rock falls, small/medium size landslides and stonewall failures. The results are now published in a paper in Tectonophysics. more

6th INQUA International Workshop on Active Tectonics, Paleoseismology and Archeoseismology – 19-24 April 2015, Pescina, Italy
2014-05-20 | in Italy 2015, Meeting, PATA days | one responseDear Colleagues and Friends,
we are pleased to announce that the 6th INQUA International Workshop on Active Tectonics, Paleoseismology and Archeoseismology will be held in Pescina (Abruzzo, Central Italy) in the period 19 – 24 April 2015.
We invite all scientists in the fields of earthquake geology, paleoseismology, archeoseismology, tsunami studies, earthquake engineering, seismic hazard assessment to join this event.
We will celebrate the centenary of the 1915 M7 Fucino earthquake, that has been one of the most devastating earthquakes occurred in the Apennines. The earthquake produced extensive surface faulting and left a strong imprint in the landscape giving rise to an incredibly rich seismological, geological and paleoseismological amount of studies in the last century.
Scientific sessions will be attended in the unique historical and cultural atmosphere of the Pescina village, followed by 2 days-field trip in the Fucino and L’Aquila area, retracing on the field the path of faults, landscapes, castles and ancient settlements. Moreover, a pre-congress archaeoseismic tour in Rome will be offered to all the participants.
Soon a specific website dedicated to this event will be available, where you will find more detailed and updated information, including information on the Participation, Travel Grants and Scientific Programme.

8th International Symposium on Eastern Mediterranean Geology (ISEMG), 13-17 October, 2014, Muğla, Turkey
2014-05-12 | in MeetingThe 8th International Symposium on Eastern Mediterranean Geology (ISEMG) will be held in Muğla from 13-17 October 2014. The symposium will take place at Muğla Sıtkı Koçman University. There are some nice sessions that deal with paleoseismology and related topics. The abstract deadline is 15 May, so if you can’t go to Busan in September, check if Turkey would be an alternative. more

Earthquakes induced/triggered by fracking, oil extraction, waste water disposal?
2014-05-08 | in Earthquake, MeetingTwo articles dealing with induced (or triggered?) seismicity caught my attention last week. Time came up with a report about “The Seismic Link Between Fracking and Earthquakes“. New studies on that topic had been presented at the SSA annual meeting in Alaska. Basically it’s now possible to link two phenomena: a) The huge increase in shale gas and oil development in Ohio, Oklahoma, and Kansas during the last few years; and b) the huge increase in earthquake activity in Ohio, Oklahoma, and Kansas during the last few years. more

The 2010 M7.2 El Mayor-Cucapah earthquake caused slip on other faults in California, too!
2014-05-07 | in EarthquakeOn 4 April, 2010, the El Mayor-Cucapah earthquake occurred in NW Baja California, Mexico. It was magnitude 7.2 strike-slip event, and the (surface) ruptures were distributed over a set of faults in the area, among them the Laguna Salada Fault. The epicentral area was under surveillance by a technique similar to DInSAR – Uninhabited Aerial
Vehicle Synthetic Aperture Radar (UAVSAR). Comparison of images from before and after the M7.2 earthquake revealed that slip occurred not only in the epicentral area and at the Laguna Salada Fault, but also on faults to the north. These findings were recently published by Donnellan et al. (2014). more
